Process dies with Sentinel-2

[matthewhanson]

Running the latest version of Acolite in a docker container I get the this message

Command 'python launch_acolite.py --cli --settings settings_file.txt --images data/input/S2B_MSIL1C_20210124T153559_N0209_R111_T19TCH_20210124T173021.SAFE/' died with <Signals.SIGKILL: 9>

The the process dies in the same point every time.

The ending of the log file looks like:

Have you seen this before. This is running on an 8-core machine with 32GB.

Hi Matthew

Have not seen this before, but it could be a memory issue for the QAA computation. This computation is done with inefficient use of memory at the moment. Especially for full tiles or merged tiles this can be an issue.

In general it helps if you provide your processing settings to diagnose a problem. ;-) Which parameters are you exporting? Does it succeed if you process at lower resolution (s2_target_res=60)?
